1. Introduction
The 24-port Managed Gigabit Ethernet Switches are standard L2 switches that meets all IEEE 802.3/u/x/z
Gigabit, Fast Ethernet specifications. The switches provide three 8-port modular slots. Each slot can
accommodate one 8-port module. A variety of modules is available for selection. They include 10/100/1000M
copper module, 100/1000M SFP module, Copper and SFP mixed modules, and Fast Ethernet fiber modules.
Different modules can be installed flexibly in one device rack. The system detects the types of the installed
modules and configures the modules automatically. With variety of modules and flexibility of installation, the
switches can meet most requirements of deployment of fiber networks no matter they are Gigabit Ethernet base,
Fast Ethernet base or even combination of both.
The switches support Telnet CLI, Web GUI, SNMP and console CLI interface for switch stack management.
The network administrator can logon the switch to monitor and configure port operating mode, Quality of
Service, and powerful L2 switching functions such as VLAN, IGMP, RSTP etc. In addition, the switches are
also featured with powerful security functions such as SSH, HTTPS, IEEE 802.1x & MAC-based
authentication, and ACL control to make them suitable for office core applications.
The following figure illustrates the switch has 3 empty slots with no module installed.

zOpening or removing covers may expose you to electrical shock.
zOnly a trained service technician should service components inside these compartments.
zIf any of the following conditions occur, unplug the product from the electrical outlet and replace the part
or contact your trained service provider:
- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow the operating instructions.
zDo not push any objects into the openings of your system. Doing so can cause fire or electric shock by
shorting out interior components.
zOperate the product only from the type of external power source indicated on the electrical ratings label. If
you are not sure of the type of power source required, consult your service provider or local power
company.

2.3 Installing Module
The steps to install a module are:
1. Unscrew and open the cover of the module slot.
2. Insert the module into the slot until it is plugged on the slot connector properly.
3. Screw the module on the front panel of the base chassis securely.
-15-

2.4 Removing the Module
The steps to remove an installed module from a base chassis are:
1. Unscrew the module first.
2. Loosen two screw brackets and pull them out as shown below:
3. Use the brackets as handles to pull the module out from the module slot connector.
-16-

4. Remove the module from the slot.
2.5 Mounting the Switch
Desktop Mounting
The switch can be mounted on a desktop or shelf. Make sure that there is proper heat dissipation from and
adequate ventilation around the device. Do not place heavy objects on the device.
Rack Mounting
Two 19-inch rack mounting brackets are supplied with the switch for 19-inch rack mounting.
The steps to mount the switch onto a 19-inch rack are:
1. Turn the power to the switch off.
2. Install two brackets with supplied screws onto the switch as shown in figure below.
After bracket mounting

2. Mount the switch onto 19-inch rack with rack screws securely.
3. Turn the power to the switch on.
2.6 Applying AC Power Supply
If the purchased switch is with AC power input, one AC power cord which meets the specification of your
country of origin was supplied in package. Before installing AC power cord to the switch, make sure the AC
power is OFF and the AC power to the power cord is turned off.

2.8 Reset Button
The reset button is used to perform a reset to the switch. It is not used in normal cases and can be used for
diagnostic purpose. If any network hanging problem is suspected, it is useful to push the button to reset the
switch without turning off the power. Check whether the network is recovered.

The button can also be used to restore the software configuration settings to factory default values. The
operations are:
Operation Function
Press the button during system boot-up and release Restore factory default settings
it after boot-up. The boot-up takes about 17 seconds
and ends with LED diagnostics.
Press the button and release during switch operation Re-boot the switch unit
2.9 Making UTP Connections
The 10/100/1000 RJ-45 copper ports support the following connection types and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3, 4, 5, EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the switch will sense the speed and use half duplex for the
connection.
Port Configuration Management
For making proper connection to an auto-negotiation INCAPABLE device, it is suggested to use port control
function via software management to set forced mode and specify speed and duplex mode which match the
configuration used by the connected device.
